EMILE DE SOLMINIHAO, OF PONT AVEN, FRANCE.

CENTRIFUGAL MACHINE FOR DRYING HIDES AND SKINS,SPENT TAN, AND OTHERMATTERS.

SPECIFICATION forming part of Letters Patent No. 305,157, datedSeptember 16, 1884.

Application filed June 4, 1884. (No model.) Patented in France January5, 1884, No. 159,532.

To all whom it may concern:

Be it known that I, EMILE DE SOLMINIHAC, of the city of Pout Aven,France, have invented an Improved Centrifugal Machine for Drying Hidesand Skins, Spent Tan, and other Matters, of which the following is afull, clear, and exact description. V

This invention relates to a centrifugal machine for rapidly dryinghides, skins, spent tan, 850., but more especially hides and skins, asthey come from the tan-pits. The machine consists of a revolvingskeleton drum formed of bars placed at a little distance apart, upon theoutside of which are spread the hides or skins, or inside of which isplaced the spent tan to be desiccated. It is lined internally with finegalvanized-iron wire-work to pre vent the escape of the tan.

In order that the invention may be more readily understood, I willproceed to describe the same with reference to the accompanyingdrawings, forming part of this specification, which illustrate oneexample of the machine, Figure 1 being a longitudinal elevation of themachine complete, and Fig. 2 a crosssec'tion of the drum.

The same letters of reference indicate the same parts in the twofigures.

Upona shaft, A, which may be either vertical or horizontal, are keyedthree cast-iron or other disks,'l3, at suitable distances apart. Theyare of equal diameter, and around their periphery are secured laths a,of wood or other material not liable to injure the hides. These lathsform the circumference of the drum, and are suitably spaced to admitofair circulating through them. The bars, are

fixed to the disks B by means of bolts whose rounded heads bear on theone side against copper hoops b and on the other against the flanges ofdisks B. The hoops I) serve to prevent contact of the hides with theiron disks B. The shaft A is provided with speedpulleys c c c, and ismounted in bearings O 0, supported by cast-iron or other standards, orupon a solid foundation of masonry.

D is a trough for receiving the water extracted by centrifugal forcefrom the spenttan or other matters placed in the drum, and serving alsoto receive the matters after drying. The bars a serve as a support foran internal net-work of galvanized iron, which prevents the escape ofthe materials placed in the drum when subjected to the action ofcentrifugal force for the purpose of extractihg the water therefrom.Access is had tothe drum, supporting the pieces of th bars cut outv bycross-strips, and hinging the hole so as to swing outward, as shown indotted lines in Fig. 2, and when closed form a part,

of the skeleton drum, as shown in Figs. 1 and 2. The hides or skins arestretched upon the outside of the drum by means of wood or copper clipsd, attached to the bars by cords in such manner that the greater thecentrifugal force the firmer will the clips grip the hide.

The machine is driven ata very high speed, so that the hide is broughtconstantly in contact with a body of cold air, and the last traces ofmoisture are driven off, even that in the formof vapor. The machinerequires only to be placed in a shed or other inclosed space, and itsspeed may be varied according to the thickness of the hides and theamount of moisture contained.

By means of this machine the hides may be brought to a commercially drycondition in an hour. The sweeping and brushing of the hides isdispensed with, as the adhering tan falls off as the drying proceeds, sothat the hides are cleaned as well as dried. The moldiness so frequentat present, which injures the appearance of the grain and deterioratesthe quality of the hide, is entirely prevented, owing to the rapiditywith which the whole contents of a pitmay be desiccated.

I claim- The centrifugal machine for drying hides, skins, spent tan, andother materials, consistmg of a rotary skeleton drum formed ofspaced-apart bars having clips or means to stretch the hides or skinsupon the circumskins, spent tan, and other matters signed by me this12th day of May, 1884.
